*1 Pr.71 = "0, 3, 5, 6, 20, 23, 40, or 43" (standard motor)
*2 Pr.71 = "10, 13, 15, 16, 50, or 53" (constant-torque motor)
*3 Pr.71 = "70 or 73" (SF-PR)
NOTE
• When the Pr.0 and Pr.12 settings are changed from their initial values, the automatic change is not performed.
• When the SF-PR motor is selected (Pr.71 = "70 or 73"), the output current may become large due to a small load by setting
Pr.81 Number of motor poles according to the number of the SF-PR motor poles.
• When the SF-PR motor is used, the output current tends to increase compared with the case where the SF-JR or SF-HR motor
is used. Depending on the load conditions, the output current may increase even though the torque boost value has been
automatically changed. When the protective function such as the electronic thermal O/L relay (E.THT, E.THM) or stall
prevention (OL, E.OLT) is activated, adjust the Pr.0 Torque boost according to the load.
CAUTION
• Make sure to set this parameter correctly according to the motor used. Incorrect setting may cause the motor and the
inverter to overheat and burn.
